Trovafloxacin Disease Interactions

There are 3 disease interactions with trovafloxacin:


Quinolones (Includes Trovafloxacin) ↔ Myasthenia Gravis

Severe Potential Hazard, Moderate plausibility

Applies to: Myasthenia Gravis

Fluoroquinolones have neuromuscular blocking activity and may exacerbate muscle weakness in persons with myasthenia gravis. Postmarketing serious adverse events, including deaths and requirement for ventilatory support, have been associated with fluoroquinolones use in persons with myasthenia gravis. Fluoroquinolones should be avoided in patients with history of myasthenia gravis.


Quinolones (Includes Trovafloxacin) ↔ Tendonitis

Severe Potential Hazard, Moderate plausibility

Applies to: Tendonitis

Tendonitis and ruptures of the shoulder, hand, and Achilles tendons have been reported in patients receiving quinolones, both during and after treatment. Therapy with quinolones should be administered cautiously in patients with preexisting tendonitis, since it may delay the recognition or confound the diagnosis of a quinolone-induced musculoskeletal effect. It is recommended to discontinue these agents if, at any time during therapy, pain, inflammation or rupture of a tendon develop and institute appropriate therapy.

Trovafloxacin (Includes Trovafloxacin) ↔ Liver Disease

Severe Potential Hazard, High plausibility

Applies to: Liver Disease, Biliary Obstruction

Trovafloxacin undergoes metabolism by the liver as well as excretion by the hepatobiliary system. Patients with hepatic impairment or biliary obstruction may be at greater risk for adverse effects from trovafloxacin due to decreased drug clearance. Therapy with trovafloxacin should be administered cautiously in these patients. The manufacturer recommends a dosage reduction in mild to moderate cirrhosis. Periodic assessment of hepatic function is advised, especially during prolonged therapy (>= 21 days), since trovafloxacin can also cause elevations of liver enzymes.

Drug Interaction Classification

The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No information available.

Do not stop taking any medications without consulting your healthcare provider.
